Multiple stop

ABSTRACT

This invention can be used as an accessory to many different types of machines, mainly cut-off saws. It makes it possible to cut a quantity of material to different lengths in one operation per set-up, compared to one length per set-up in past inventions. The gauge operates by pushing the material to be cut alongside the guide bar, up to the desired stop. By pushing the material against the guide bar and side of the desired stop-pin, thus depressing the undesired stop-pins into the housing. The stops can be positioned anywhere within the guide bar, and can be turned within 360 degree circumference to suit the size of material being cut, drilled, etc., or to fit into grooves, holes or recesses in the material.

The most used jig now isa block fastened on with a clamp to a stop bar. Past inventions haveemphasized fast setups and measurements, but can only cut one length perset-up. If several lengths have to be cut at one time, the setup andmeasurements have to be changed. This procedure is time consuming andtroublesome. Often two or more different lengths have to be cut out ofone piece. For example: door headers, sizes 24 inch, 26 inch and 32inch, have to be cut out of an 84 inch piece. Sometimes 100 pieces ofeach of the above mentioned sizes have to be cut at the one time.

For example: a person has to pick up the 84 inch piece, cut off onepiece 32 inch, lay down the pieces left over, pick up the left overpieces and cut off one piece 26 inch, lay them down on a differentplace, and finally pick up the left over pieces and cut the 24 inchpiece, handlingit three hundred times and using a lot of space and time.I have found that time and space can be saved by being able to outdifferent lengths at the same time without having to change the set-upof the gauge as in my invention.

FIGS. 1 and 2 in the drawing illustrate the embodiments of my inventionand are described below:

FIG. 1 is a front view of the assembled invention.

FIG. 2 is a section cut through the centre of a type A Stop.

The gauge illustrated comprises a channel 1. which is fastened to thework table or cross-slide of a machine, or to the machine itself byusing bolts or screws. It also serves as guide rail for the material tobe cut or drilled, and many more uses. The Stops 2. can be slid in onthe end and placed in difierent positions as desired, by tightening aset screw 6 with an Allen wrench, thus pushing it tight against thefront of the channel and locking it securely into place.

The type A Stop consists of a retractable stop pin 3, a spring 4, a plug5 which closes the hole. The hole is of cylindrical shape drilled fromthe back of the Stop 2. (housing). It is narrower in the front so thepin 3 cannot slip out completely, and serves also as pin guide. 6 is aset screw for fastening the Stop 2. into any desired position within thechannel (guide bar).

The type B Stop, first stop in FIG. 1. is necessary if the lengths to becut differ by less than one inch. lt is adjusted by turning it insidethe channel within a 360 circumference into the desired position. Thetype A Stops can also be turned into different positions to suit thesize of material to be cut or to fit into grooves, holes or recesses inthe material.

The material used for the gauge can differ to suit the applicationwhether it is stationary or portable. On stationary gauges, hard goodquality steel should be used because it is supported by the machine orwork table. The material used for a portable gauge may need to belighter and could be of good quality aluminum, or strong hard plastic.The stops could be of a variety of different shapes other than roundalso the stop-pins could be different to suit a specific application.

The gauge operates by pushing the material to be cut alongside the guidebar, up to the desired stop. By pushing the matriial against the guidebar (channel) and the side of the desired stop-pin thus depressing theundesired stop-pins into the housing, the stop-pins repositionthemselves automatically when material is removed.

The embodiments of the invention in which an exclusive property orprivilege is claimed are defined as follows:

l. A gauge for use with machines for duplicating a plurality ofdifferent lengths or locations in material per set up, comprising incombination a length of channel including an open front side, aplurality of pinguides slideably engageable within said channel, a setscrew in said pinguide reacting between said pinguide and front side ofchannel to detachably and adjustably clamp said pinguides in saidchannel, said pinguides include at least one retractable pin mountedtherein, a spring in said pinguide for said pin, normally biasing saidpin to a position extending from said front side of channel butpennitting said pin to move into said pinguide by compressing saidspring when material is pushed against said pin, said pins repositionthemselves automatically when material is removed, said pinguides beingrotatable through 360 degrees within said channel for positionadjustment of said pins.
